Everything you always wanted to know about potassium

It is well known to any farmer that potassium (K) supply strongly impacts on nitrogen usage efficiency and disease resistance of crops but the molecular processes underlying these interactions are poorly understood. Using Arabidopsis thaliana as a model species we have over the last years assembled a large dataset detailing the effects of K deficiency on ion homeostasis, as well as primary and secondary metabolism. We have further analysed regulatory mechanisms supporting plant adaptation to K deficiency at the level of hormones, transcripts and enzyme activities. Based on this information I will present our current molecular models explaining K-nitrogen and K-disease interactions observed in the field.
